Open Access research with a real impact on health...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the Physical Activity for Health Group based within the School of Psychological Sciences & Health. Research here seeks to better understand how and why physical activity improves health, gain a better understanding of the amount, intensity, and type of physical activity needed for health benefits, and evaluate the effect of interventions to promote physical activity.

Abstract

The use of a large solar shield located sunward of the Sun-Earth interior Lagrange point is considered to offset increases in mean global surface temperature due to enhanced greenhouse warming. The three-body mechanics of the problem are investigated to optimize the shield location, thus minimizing the shield mass and improving on previous studies of this concept. While shield mass is minimized, the required mass is still of order 1011 kg to offset an enhancement of greenhouse warming of order 2 K. Clearly, such schemes require significant technological capabilities, although the optimization presented in this paper reduces the scale of the problem to some extent.
